The same className is contained in div and input

[shinvik]

The class name is declared in the object in renderInput method of Select.js

const inputProps = Object.assign({}, this.props.inputProps, {
// ... other code
  className: className,
// ... other code
});

The same class name is contained in div and input

// autosize === false
return (
  <div className={ className }>
    <input {...inputProps} />
  </div>
);
